FIELD OF THE INVENTION

The present invention relates generally to a structure of a modular shelf rack, and more particularly to a rack that does not need screws when putting it up or taking it down, which makes it more convenient and efficient.

BACKGROUND OF THE INVENTION

The improved shelf rack of the present invention is made by different rods in each shelf, and by connecting each part to make the entire structure. There are many structures of modular shelf racks; however, the conventional structure thereof cannot be assembled quickly when connecting the parts of the shelf together, and it needs some screws to position it most of the times. Therefore, it is not convenient and not efficient when assembling the shelf.

Thus, to overcome the aforementioned problems of the prior art, it would be an advancement in the art to provide an improved structure that can significantly improve the efficacy thereof.

To this end, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.

BRIEF SUMMARY OF THE INVENTION

The improved facts of the present invention are presented herein.

The present invention is made by its bar-type side rack 1A 1B, the lower stationary rack 20, upper stationary rack 30, and the structure of the assembled storage bag can be made in the simplest and lightest way, which can greatly reduce the material and cost, and meet the preferred industrial needs. The lower stationary rack 20 is placed on the bottom of the two side rack 1A 1B using the hook 21 and vertical blocker 22. The upper stationary rack 30 is positioned quickly by putting the slip-on positioning part 31 over the top of the two side racks 1A 1B so that the process of the assembling of the shelf rack does not need screws or other positioning parts to achieve more convenient and effective assembling.

Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.

DETAILED DESCRIPTION OF THE INVENTION

The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.

As shown in FIGS. 1-4, there is a structure of modular shelf rack, this embodiment being for description only, and not being limited to this structure when applying for the patent. The structure of the modular shelf rack comprises the following.

A bar-type side rack 1A 1B is standing vertically, and the bar-type side rack is made by a single bar frame 10. Among them, the top and bottom of the two side racks 1A 1B have an upper positioning part 11 and lower positioning part 12 with pre-determined height, the lower positioning part 12 being a horizontal rod.

A lower stationary rack 20 is placed horizontally between the bottom of the two side bars 1A 1B, and a hook 21 and a vertical blocker 22 are placed two sides of the lower stationary rack 20. The hook 21 mentioned here can be hooked to the lower positioning part 12 at the bottom of the two side racks 1A 1B, and the vertical blocker 22 is for the inside of the two side racks to lean against when they are standing vertically. The vertical blocker 22 of the embodiment is formed by the outside of two horizontal frames that are spaced from top to bottom.

An upper stationary rack 30 is placed in between the top of the two side racks 1A 1B, and the slip-on positioning part 31 is placed on its two sides. The slip-on positioning part is placed on the vertical frame of the top of the two side racks 1A 1B to position the top of the two side racks 1A 1B.

Among them, the upper positioning part 11 on the top of the side rack 1A 1B can be a horizontally rod or rail or protruding block. The upper positioning part 11 shown in FIGS. 1, 2 is a rail, and the upper positioning part 11B shown in FIG. 5 can be a protruding block.

Among them, the space between the top and bottom of the side racks 1A 1B have a pre-determined rail 40, and the placement of the rail is for the shelf or drawer to slide. As shown in FIG. 6, the rail 40 is for the drawer 50 to slide. As shown in FIG. 7, the upper positioning part 1C is a horizontal rod for a hanger 61 at the top of the storage bag 60.

Among them, as shown in FIGS. 1, 2, the upper stationary rack 30 can be a frame, which includes an external frame bar 301 and at least two internal supporting bars 302, and the two internal supporting bars are placed on two sides of the external frame bar 301 in parallel to form the slip-on positioning part 31 in between.

Among them, the upper stationary rack 30B as shown in FIG. 8 is a plate (such as wooden plate, plastic plate and metal plate), and rectangle through holes are set up on both sides of the upper stationary rack 30B to form the slip-on positioning part 31B. The upper stationary rack is placed in as shown in FIG. 9, and an upper positioning part 11D is placed on the upper part of the side rack 1B for positioning. The lower stationary rack 20B of this embodiment is a plate as well.

Through the above structure and design, the operation of the present invention disclosed herein is explained as follows.

As shown in FIGS. 1, 2, when the shelf rack of the present invention is assembled, it is to put the lower stationary rack 20 between the bottoms of the two side racks 1A 1B, and when the two side racks are in vertical angles, the hook 21 may be placed on both sides of the lower stationary rack 20 on the lower positioning part 12 of the two side racks 1A 1B. The vertical blocker 22 is placed against the inside pf the two side racks to form a two-way limiting function so that when the top of the two side racks 1A 1B are pushed in opposite direction, it stores external elastic force. Then, the upper stationary rack 30 is positioned by putting the slip-on positioning part 31 unto the two side racks 1A 1B to position the upper part of the two side racks 1A 1B, using the principle that the two side racks mentioned above can tighten the upper stationary rack 30. By so doing, the two side racks 1A 1B, the lower stationary rack 20, the upper stationary rack 30, are positioned and do not need other positioning parts for assistance.

As shown in FIGS. 10, 11, there is another embodiment of the lower stationary rack of the shelf rack of the present invention. The main frame of the lower stationary rack 20C of the embodiment is made by a bended rod, and the vertical blocker 22B that is formed and shaped at the corners.
